Every once in a while a project comes along with that magical power to consume your time and attention for many months. When you finally complete it, you feel sorry that you don’t have to do anything ...

One of the nicest amenities of interpreted programming languages is that you can test out the code that you’re developing in a shell, one line at a time, and see the results instantly. No matter how ...

There are several ways to readmultiple switch inputs using areduced number of microcontroller-unit(MCU) pins. For example, you can usean analog MCU pin to read multipleswitches by assigning a unique ...

The circuit in this Design Idea provides a way to convey mixed analog and digital inputs into a microcontroller using one input pin. The output of the circuit connects to a micro-controller's ...

Microcontroller port pins can typically be driven either high or low, or else be put into an "input" or high-impedance state. This circuit uses the three states to drive two separate LEDs with one ...

Meet the Raspberry Pi Pico 2 W, a tiny board designed around a microcontroller that lets you build hardware projects at scale. Raspberry Pi is once again using the RP2350, its own well-documented ...
